Decibels Reduction: expression used to indicate the sound insulating properties of a wall or floor panel
{"Image DocumentName": "Decibels Reduction: expression used to indicate the sound insulating properties of a wall or floor panel", "Image ImageDescription": "Sound Transmission Loss: STL, the number of decibels which sound loses when transmitted through a wall or floor. Sound Absorption: capacity of a material or object to reduce sound waves by absorbing them, these sounds are otherwise reflected and cause excessive reverberation and build up of intensity within that area. Noise Reduction Coefficient: NRC, the sound absorption of acoustical materials is expressed as the average percentage absorption at the four frequencies which are representative of most household noises, these frequencies are 250, 500, 1000, and 2000 cycles/second. Sound Transmission Class: STC, single number which represents the minimum performance of a wall or floor at all frequencies, the higher the STC number, the more efficient the wall or floor will be in reducing sound transmission.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
